I understand by your e-mail your car originated via Hornburg in CA, not that Hornburg was a source of hardtops fitted to the XK120 range of cars. I am not aware of any Jaguar factory accessory hardtop fitted to the XK120-XK140-XK150 range of cars. There have been a few aftermarket suppliers of fiberglass hardtops fitted to XK cars, but none were factory produced. Hornburg was the authorized dealer of Jaguar cars West of the Mississippi, but to my knowledge never a source of aftermarket hardtops. I would think in the US market, suppliers of aftermarket tops like Parrish would have their products sold occasionally on eBay or other sources. Good Luck!!

Cheers, Mark

I’m a XK 120 enthusiast and i search a hardtop to the OTS
XK 120. It was from Charles Hornburg made for the US Market.
Do you have an idea where i could find one? )
